...missing, so I get an error and my program stops. Is there a way to check for a null pointer analogous to C, so that I can simply skip non-existent filenames?

...bly, the best solution for me may be to modify metaplot for the Hunter-Schmidt method. BTW, the manual to the program Meta-Analysis 5.3, is also very helpful, see: http://userpage.fu-berlin.de/~health/meta_e.htm Further suggestions in this direction are greatly appreciated.

Dear all Just for fun, I have just downloaded the paper mentioned below and checked it with R-1.6.1. Everything is ok with exception of Table 2b, where I get always 1 instead of 0.5: > pbinom(1e15,2e15,0.5) [1] 1 Which value should be correct?

...oes this result in an improved memory model for R (or do I get something wrong)? Is it worth using this new version? I have to work with very large tables (about 300,000 rows) so any improvement in the memory model of R would probably be an advantage. Thank you in advance for your help.

Hi-- While I agree that we cannot agree on the ideal algorithms, we should be taking practical steps to implement microarrays in the clinic. I think we can all agree that our algorithms have some degree of efficacy over and above conventional diagnostic techniques. If patients are dying from lack of diagnostic accuracy, I think we have to work hard to use this technology to help them, if we

Hi, all. I'm trying to cluster 12,500 objects using hclust from package mva. The distance matrix takes up nearly 600 MB. The distance matrix also needs to be copied when being passed to the fortran routine that actually does the clustering (it's modified during the clustering), so that's 1200 MB. I'm actually on a machine with 2.5 GB of memory (and nothing else running), so I
